Title: Efficient arrangement for coupling light between light source and light guide
Inventor: BUELOW ROGER F II
IPC: F21Y101/00
Filed: 2000-12-01
Granted: 2010-03-23
Abstract: An efficient arrangement for coupling light between a light source and at least one light guide comprises a light source (12) having a bulbous region (30) and electrical in-leads (14, 16) extending into the bulbous region. A generally tubular, hollow coupling device (24) with an interior light-reflective surface (22) receives light from the source at an inlet and transmits it to an outlet (27). The coupling device increases in cross sectional area from inlet to outlet in such manner as to reduce the angle of light reflected from the surface as it passes through the device. A thermal-isolating region (26) has an inlet positioned in proximity to an outlet of the coupling device and has an outlet for passing light to an optical member (28). The thermal-isolating region comprises one or more members. The foregoing can achieve high efficiency and considerable compactness while using a non-"point-like" light source.

Abstract: The top (6) of a disposable weight-reducing suction cup (1) adapted to be intimately contacted with a weigh-reduction subject portion (8) is provided with a projection (24) and a thin-walled portion (35) disposed in the region of the inner surface of the cup (1) opposed to the projection (24). The cup (1) is intimately contacted with the weight-reduction subject portion (8), a nd then it is evacuated for suction by a pressure reducing valve (16) to dissipate the subcutaneous fat in the weight-reduction subject portion (8). After suction, this projection (24) is bent to destruct the thin-walled portion (35) to form a hole in the top (6), thereby equalizing the pressure in the cup with the outside pressure. This allows easy removal of the cup (1) from the weight-reduction subject portion (8). The absence of a complicated reduced pressure releasing mechanism results in an inexpensive disposable weight-reducing suction cup. Further, the barrel (4) of the weight-reducing suction cup (1) to be intimately contacted with the weight-reduction subject portion (8) is provided with a deformable portion (25) composed of a recess (20) and a thin-walled portion (18). The deformable portion (25) serves as a pressing portion adapted to be easily inwardly deformed and crushed when the interior (42) of the cup (1) is evacuated, and to laterally press the weight - reduction subject portion (8) to effectively dissipate subcutaneous fat.</SD OAB>

Granted: 2009-05-26
Abstract: A micro-optic device including a complicate structure and a movable mirror is made to be manufactured in a reduced length of time. A silicon substrate 42 and a single crystal silicon device layer 43 with an intermediate layer 41 of silicon dioxide interposed therebetween defines a substrate 31 on which a layer 44 of mask material is formed (Fig. 14A) and is patterned to form a mask 45 having the same pattern as the configuration of the intended optical device as viewed in plan view. A surface which is to be constructed as a mirror surface is chosen to be (100) plane of the silicon crystal. Using the mask 45, the device layer 43 is vertically etched by a reactive ion dry etching until the intermediate layer 41 is exposed (Fig.  14C).    Subsequently, using KOH solution, a wet etching which is anisotropic to the crystallographic orientation is performed with an etching rate which is on the order of 0.1 µm/min for a time interval on the order of ten minutes is performed to convert the sidewall surface of the mirror 4 into a smooth crystallographic surface (100). Subsequently, the intermediate layer 41 is selectively subject to a wet etching to remove the intermediate layer 41 only in an area located below the movable part of the optical device (Fig. 14D).
